Although rain and strong winds will continue in the northwest, Scotland and Northern Ireland.

When will the warm weather hit?

"The warmer weather will kick in from mid-week onwards, and we could see 21C in parts of the country by Thursday,” Jim Dale, meteorologist for British Weather Services, said.

“High pressure building from the Continent will bring a change from the wetter, windier weather to drier, sunnier conditions,” he added.

Mr Dale notes Hurricane Sam has much to do with the warm conditions we will see this week.

"The remains of Hurricane Sam will veer towards Iceland as it moves across the Atlantic, this will mean it will miss the UK but pull warm air in from the south” and “as we are now in October, we can call this an Indian Summer,” he said.

"This could last through the week or possibly longer into the mid-month when we expect to see a return to something more usual for the time of year."
